Abstract/Contents:"Three selections (MN#42, #184 & MN#208) were approved for release by the Minnesota Agricultural Experiment Station-Horticultural Plant Release Committee.; Decision has been reached to concentrate on introduction of MN#42.; A new, 5 acre Breeder's seed planting of MN#42 was planted in early Nov. 94.; Seed field plantings of 1 acre each of Minnesota numbered selections, #42 and # 184, and 2 acres of #208 was seeded on November 12, 1993 at as site in the Willamette Valley, Oregon under agreement with the Peterson Seed Company. Certified Perennial Ryegrass was grown on the land for the last four years. The land has never been in bluegrass production. Planting was completed at a rate of 1 pound of seed per acre. The Grower indicated that 12 Nov. was far too late for an intended seed crop the following summer. Two methods of seed harvest were tried, one with a grass catcher and one with a standard windrower. The seed crop was respectable and the windrower worked well. MN#42 produced the most uniform heading and least shattering. MN#184 and MN#208 exhibited some uneven ripening and shattering. This may indicate the possibility of two harvest a season.; Conclusions: 1) the late planting was successful; 2)Harvesting can be accomplished with standard equipment; and 3) each selection produced sufficient seed to warrant continued seed production.; Crosses between annual & perennial types of Poa indicate a 3 : 1 ratio of inheritance of continuous flowering to seasonal flowering.; Results indicate that 4-8°C is the optimal vernalization temperature & that vernalization requires 10-12 weeks. It appears that critical photoperiod is between 10 & 12 hrs. and that 4 to 6 leaves are required for reception of induction stimuli.; The top 2% of 1994 progeny were selected for further evaluation.; Interspecific crosses between Poa supina and Poa reptans produced some unique plant types that were selected for further evaluation.; New, promising materials, performing well under putting green conditions include progeny for F4 generations of MN#184 X 117 an [and] 234 and F3 progeny of a MN#42 X MN#184 cross.; Seed was furnished to the University of Nebraska for replicated evaluation and North Carolina State, Raleigh for an overseeding evaluation planting.; 1995 plans will concentrate of seed production, PVP, and establishing substantial evaluation plantings across the USA and in Canada."
